With a DMM

WARNING: This page is about a different car, the 2007 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove the power feed (i.e. fuse, control module) from the suspect circuit.
  2. Disconnect the load.
  3. Set the rotary dial of the DMM to the ohm position.
  4. Connect one lead of the DMM to one end of the circuit to be tested.
  5. Connect the other lead of the DMM to a good ground.
  6. If the DMM does NOT display infinite resistance (OL), there is a short to ground in the circuit.
